Powerpoint hyperlink

So... if you select a text to attach a hyperlink to it, it's hard to change its style and form.
however, what I suggest is to leave your text as is and overlay a rectangle to which you will apply the hyperlink.
then you remove the border and color from this rectangle, and by clicking on the text, you will be redirected to the web page or file of your choice
WITHOUT modifying the text below.

I'm not sure if I've been clear... but that's the idea.

good luck !!!

it's them who provide the solution... I don't think there are any others.

I think the best solution is to select the text and change the hyperlink color in the font settings to match the background color.
I tried setting underline to none but it doesn't work.

Thank you, but I want to keep the link while removing the underline.

you just have to right-click and remove the hyperlink.
I think that’s enough
Good luck
